Fish Hawk Electronics was one of the first businesses to provide sonar depth finders for fisherman in the late 1960s. Pacific salmon were being supplied and established in adjacent Lake Michigan about the same time. These fascinating new species were particularly sensitive to water temperature, as anglers rapidly discovered. To determine the fish's optimal water temperature range, Fish Hawk Electronics developed a hand-held water temperature gauge with a 200-foot cord. Downriggers gained popularity as the Great Lakes salmon fishing expanded. Fishermen discovered that the motion of their lures was greatly impacted by underwater currents, which also have a significant impact on their haul. The developers at Fish Hawk created the first wireless device that informed fishermen of the speed and water temperature at a certain depth using their sonar knowledge.
